Description

  The present invention relates to a traffic monitoring system that allows a pedestrian and a passing vehicle in a local area to perceive each other.

  With the development of mobile phone functions and infrastructure, the location of mobile phones on a map can be specified fairly accurately. The same applies to a navigation device mounted on a vehicle. And with these increased penetration rates, use pedestrian mobile phones and vehicle navigation devices to avoid contact and collision between pedestrians and vehicles or vehicles at intersections with no traffic lights and poor visibility Much has been studied.

  The pedestrian detection system for a vehicle described in Patent Document 1 transmits pedestrian information including current position information and acceleration information of the pedestrian from a portable transmitter that the pedestrian has, and is mounted on the vehicle. Receive pedestrian information directly or via nearby base stations. The determination unit provided in the receiver determines whether the pedestrian is running or approaching from the received pedestrian information, and if it is pedestrian information necessary for driving the vehicle, by voice or display Notify the driver.

  Further, the position information of the vehicle is received by the portable transmitter, and the pedestrian information is transmitted from the portable transmitter when the vehicle is within a radius of 100 m around the pedestrian. Furthermore, in the case of this vehicle pedestrian detection system, the vehicle has an automatic deceleration device, and if it is determined that the received pedestrian information is necessary information for safe driving, the vehicle running speed is reduced by fuel cut or the like. Decelerate.

  The pedestrian pop-out alarm system described in Patent Document 2 is installed by receiving a signal of a transmitter carried by a pedestrian with a receiver installed at the gate of the building or near the inside of the gate of the building. The presence or absence of a pedestrian is detected by analyzing the image captured by the surveillance camera, and a detection signal is sent to inform the vehicle approaching the gate of the building that there is a person. In the vehicle that received the report, the driver is warned by voice, buzzer sound, and display device. In addition, a pedestrian inside the building gate is notified that the vehicle is approaching directly or through a receiver carried by the pedestrian, such as a warning by a sound or a buzzer sound. Further, the warning means for the driver provided in the vehicle is interlocked with the brake electronic control device of the vehicle, and decelerates to a predetermined speed or less when the detection signal is received.

  The driving assistance apparatus described in Patent Document 3 receives a radio wave started from a mobile communication terminal such as a mobile phone held by a pedestrian or a bicycle rider in the vicinity with a receiver mounted on a vehicle. By monitoring the strength of the received signal, it is determined whether or not the owner of the mobile phone is nearby. The vehicle further includes an in-vehicle camera that detects the driver's line of sight. Based on whether the driver is operating the brake or whether the driver is looking at the mobile phone owner, it is determined whether the driver is aware of the pedestrian and depending on the situation. To announce warnings, sound horns, and activate brakes.

  The driving support device described in Patent Document 3 includes an external communication device. Mutual communication is performed between neighboring vehicles to prevent collision between vehicles. Furthermore, the external communication device communicates with peripheral external devices. This external device is connected to the exchange of the mobile phone, and when receiving the current position of the vehicle and the notification command transmitted from the external communication device of the vehicle, the current position of the vehicle and the location information of the mobile phone stored in the exchange Based on the above, a mobile phone in the vicinity of the vehicle on which the external communication device is mounted is specified and a call is made.

  A vehicle-to-vehicle communication system, an in-vehicle communication device, and a portable communication device described in Patent Document 4 directly communicate wirelessly between an in-vehicle wireless communication device mounted on a vehicle and a portable wireless communication device carried by a pedestrian, and vehicle travel information Based on the position information of the pedestrian, the driver is notified or warned that the pedestrian is approaching. Moreover, the warning which notifies that the vehicle is approaching is output to the output part of the portable communication apparatus which the pedestrian who the vehicle is approaching possesses.

  The techniques described in these patent documents 1-4 directly link a navigation device mounted on a vehicle and a communication terminal carried by a pedestrian to notify or warn the driver of the vehicle, and further to a pedestrian. Notifications are also made. At this time, the vehicle and the pedestrian are moving, and each state changes from moment to moment. The state of the vehicle can be estimated to some extent by the driver by detecting the vehicle speed, brake operation, steering wheel angle, direction indicator operation, and the like with sensors. However, the state of a pedestrian can be determined only by a change in the position information of the communication terminal. Therefore, in order to ensure that the vehicle and the pedestrian do not collide with each other, it is necessary to warn excessively or extremely limit the speed of the vehicle.

  Since there are few objects that need to be monitored at the same time in places with low traffic, it is not difficult to predict and warn each other about collisions, and it is easy for the driver who receives the warning to identify the object. It is. However, if there are many pedestrians, it will be difficult to identify the warned target. Furthermore, if there are many things that limit the field of view, such as a vehicle that travels forward and backward or a vehicle that is parked or stopped, it is difficult to identify the object that has been warned.

  In such a situation, if the technique described in Patent Documents 1-4 is adopted, the speed of the vehicle is extremely reduced when the relative distance to the pedestrian is reduced, which may cause traffic congestion. In these systems, it is considered that not only the driver of the vehicle cannot completely predict the next movement of the pedestrian but also the system cannot grasp whether the driver has recognized the notified warning. As a result, the vehicle must be controlled to be safer with respect to unpredictable pedestrian behavior, resulting in an excessive response.

  Therefore, the present invention provides a traffic monitoring system that promotes smooth traffic by recognizing the presence of other moving bodies approaching a plurality of moving bodies in a local area.

  A traffic monitoring system according to an embodiment of the present invention includes an information communication terminal and a monitoring device. The information communication terminal is provided in each of at least two moving bodies that move in a local area including at least a road on which a vehicle passes, and outputs the current position information and the type of the moving body as moving body information. The monitoring device calculates the moving direction and moving speed of the moving body based on the position information of the information communication terminal, and sends the moving direction and moving speed of the moving body to each of the information communication terminals of the moving bodies approaching each other in the local area. Thus, the approach information including at least the azimuth in which the counterpart mobile body approaches, the predicted time until the counterpart mobile body is encountered, and the type of the counterpart mobile body as the counterpart mobile body information is notified. Then, the monitoring device requests that the confirmation of the approach information be input to the information communication terminal as response information, and reports the response information to the information communication terminal of the counterpart mobile unit.

  What is input as response information is not limited to a button operation indicating confirmation. If the moving body is a vehicle, reduce the accelerator pedal opening, depress the brake pedal, decelerate it, operate the steering wheel, etc. Moving away from the direction can be handled as response information.

  At this time, when response information is not input from each of the mobile information communication terminals approaching each other, the monitoring device outputs warning information to each information communication terminal. In addition, when at least one of the moving objects approaching each other is a vehicle including an electronically controllable braking device linked to the information communication terminal, and no response information is input from each of the information communication terminals, the monitoring device While outputting warning information to the information communication terminal, the vehicle braking device is operated to decelerate.

  In addition, when all the moving objects that are close to each other are equipped with electronically controllable braking devices linked to the information communication terminal, and no response information is input from each of the information communication terminals, the monitoring device Warning information is output to the information communication terminal, and a braking device for a vehicle having a low traffic priority in the local area is operated to decelerate the vehicle. Here, “traffic priority” means priority at an intersection determined according to the road traffic law, and may include emergency vehicles.

  Alternatively, at least one of the moving objects approaching each other is a pedestrian, and the rest is a vehicle including an electronically controllable braking device and a horn linked to the information communication terminal, and the response information from the information communication terminal possessed by the pedestrian Is not input, the monitoring device sounds the horn of the vehicle to output warning information to the information communication terminal and operates the braking device to decelerate.

  At this time, the information communication terminal equipped in the vehicle is a navigation device, and approach information and warning information for the driver of the vehicle are displayed on the display device of the navigation device. Moreover, the information communication terminal possessed by the pedestrian is a mobile phone, and approach information and warning information for the pedestrian are notified with vibration.

  The traffic monitoring system further includes a camera for photographing the local area, an image analysis device, and an alarm device. The image analysis apparatus extracts a moving body that is not equipped with an information communication terminal based on the video acquired by the camera, and sets position information and a type of the moving body. Alarms are installed at major locations within the local area. When at least one mobile body not equipped with the information communication terminal is included in the mobile bodies approaching each other, and no response information is input from the information communication terminal, the monitoring device An alarm is output from an alarm device in a direction in which a mobile object not equipped with an information communication terminal approaches.

  In order to manage vehicles parked on the road, if the information communication terminal stops outputting mobile body information at a point where the mobile body has stopped, the monitoring device assumes that the mobile body is in that position. The approach information is notified to the information communication terminal of another moving body approaching.

  In addition, when there is an adjacent traffic monitoring system, in order to smoothly process approach information related to a moving body that moves across two local areas, the monitoring device is an adjacent monitoring device of at least one adjacent traffic monitoring system. Work with. And as a result of calculating the moving speed and moving direction based on the moving body information of the boundary moving body located in the boundary zone of each other local area, the boundary moving body approaches any other moving body in the local area under its jurisdiction. If not, the moving body information of the boundary moving body is transferred to the adjacent monitoring device.

  According to one aspect of the traffic monitoring system of the present invention, the direction in which the counterpart mobile body approaches the information communication terminals of mobile bodies approaching each other, the predicted time until the counterpart mobile body is encountered, In addition to notifying each information communication terminal of the type of the other party's mobile body as the other party mobile body information, the information communication terminal is requested to input that the information has been confirmed as response information. Then, the response information is reported to the information processing terminal of the counterpart mobile body.

  Thus, by inputting the response information, it is confirmed that the moving bodies on the other side approaching each other are mutually recognized before the moving bodies encounter each other. Since each other is notified that there is an approaching partner, it is easy to predict the other party's movement, and it is easy to prevent accidents such as contact or collision. Moreover, since both approaching sides recognize the other party, there is no need to forcibly decelerate, so the traffic flow becomes smooth. Furthermore, pedestrians walking alongside a road without a sidewalk will not be surprised when they are suddenly approached when they are overtaken by cars, motorcycles, or bicycles from behind.

  According to the traffic monitoring system of the invention in which the monitoring device outputs warning information to each information communication terminal when response information is not input from each of the information communication terminals of the moving objects that are close to each other, the moving objects that are approaching Since the warning information is re-notified by the warning information, contact and collision are easily avoided. The warning information may be left by vibration or display, in addition to being notified by a warning sound or warning announcement, or a combination thereof.

  In particular, when at least one of the moving bodies approaching each other is a vehicle having an electronically controllable braking device linked to an information communication terminal, the braking device is activated and the vehicle is decelerated unless response information is input. According to the traffic monitoring system of the invention, it is possible to respond faster than the driver. Moreover, since kinetic energy also becomes small by decelerating, damage, such as a contact or a collision, can be suppressed small.

  Furthermore, in the case where vehicles approaching each other are equipped with electronically controllable braking devices linked to an information communication terminal, the braking device of a vehicle having a low traffic priority is operated and decelerated in the local area. According to the traffic monitoring system, for example, a traffic flow becomes smooth by passing a vehicle with a high traffic priority first at an intersection without a traffic light.

  At least one of the moving bodies approaching each other is a pedestrian, and the rest is a vehicle equipped with an electronically controllable braking device and a horn linked to an information communication terminal, and response information is input from the information communication terminal possessed by the pedestrian If not, according to the traffic monitoring system of the invention in which the monitoring device rings the vehicle horn, outputs warning information to the information communication terminal and activates the vehicle braking device, the vehicle is approaching the pedestrian by the horn And a warning is also notified to the information communication terminal. Furthermore, since the speed of the vehicle is reduced, there is a high possibility of preventing mutual contact and collision.

  According to the traffic monitoring system of the invention in which the information communication terminal equipped in the vehicle is a navigation device and displays the approach information and warning information on the display device to the driver of the vehicle and announces by voice. By adding an extended function to, this traffic monitoring system can be easily accommodated. Similarly, according to the traffic monitoring system of the invention in which the information communication terminal equipped with the pedestrian is a mobile phone and reports the approach information and warning information to the pedestrian with at least vibration, an extension function is added to the existing equipment. By adding, for example, an application, it is possible to easily correspond to this traffic monitoring system. By setting many information communication terminals to be compatible with this traffic monitoring system, it is easy to detect moving objects approaching in the local area, and the probability of preventing accidents such as contact and collision is increased.

  The information communication terminal further includes a camera, an image analysis device, and an alarm device, and at least one mobile body not equipped with the information communication terminal is included in the mobile bodies approaching each other, and no response information is input from the information communication terminal According to the traffic monitoring system of the invention that outputs warning information from an alarm device in a direction in which a mobile body not equipped with an information communication terminal approaches a mobile body equipped with an information communication terminal, for a mobile body equipped with an information communication terminal It is also possible to detect a partner approaching without being equipped with an information communication terminal. In addition, by outputting warning information from a warning device to a mobile body equipped with an information communication terminal, the mobile body side not equipped with the information communication terminal is notified that another mobile body is approaching. Therefore, the probability of preventing accidents such as contact and collision is increased.

  If the information communication terminal stops outputting the mobile object information at the point where the mobile object stops, the monitoring device will approach the information communication terminal of another mobile object that approaches this mobile object as if the mobile object is in that position. Since the vehicle parked on the road can be continuously monitored, accurate access information can be provided to other moving objects approaching.

  In addition, the monitoring device is linked with the adjacent monitoring device of at least one adjacent traffic monitoring system, and the boundary moving body located in the boundary zone of each local area is one of the other moving bodies in the local area under its jurisdiction. According to the traffic monitoring system of the invention in which the moving body information of the boundary moving body is transferred to the adjacent monitoring device when the two are not approaching, the approach information relating to the moving body moving across the two local areas is processed smoothly without omission. be able to. In addition, the traffic monitoring system service for the boundary moving body can be prevented from becoming complicated.

The figure which shows typically the traffic monitoring system of 1st Embodiment which concerns on this invention. The flowchart of the control which the monitoring apparatus of the traffic monitoring system of FIG. 1 performs. The figure which shows typically the traffic monitoring system of 2nd Embodiment which concerns on this invention.

  A traffic monitoring system 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. This traffic monitoring system 1 is provided with at least a road on which vehicles pass, for example, an intersection K1 where no traffic light as shown in FIG. 1 is installed, a road R1 or an alley R3 with poor visibility due to approaching buildings, or a sidewalk. It is installed in a local area L including roads R1, R2, etc. that are not provided. The traffic monitoring system 1 is a monitoring device that communicates directly or indirectly from the information communication terminals 11 respectively installed in at least two moving bodies 10 moving in the local area L and the moving bodies 10 in the local area L. 20 is included.

  The information communication terminal 11 outputs the unique identification information, the current position information, and the type of the moving body 10 as moving body information. What is assumed as the moving body 10 moving in the local area L is an automobile (vehicles 10A, 10C, 10D) and a motorcycle equipped with a navigation device as the information communication terminal 11, and a mobile phone as the information communication terminal 11. It includes at least a pedestrian (10E, 10F, 10G, 10H, 10M) or a bicycle (vehicle 10B), a motorcycle, and a car (vehicle) on which a person equipped with a mobile phone is riding. The pedestrian includes a runner (10H) who performs jogging. Pedestrians and runners may be managed separately from differences in moving speed.

  The information output as the type of the mobile object 10 includes whether it is a navigation device or a mobile phone. In the case of a mobile phone, a preset condition indicating which mode is a vehicle, a motorcycle, a bicycle, or a pedestrian (runner) may be output as the type of the mobile body 10. In particular, in the case of a mobile phone, it is desirable that these setting modes can be switched by a simple operation, and an automatic mode that is discriminated by the monitoring device 20 based on the moving speed may be included.

  The information communication terminal 11 may be a device other than a navigation device or a mobile phone as long as it is a device that can communicate during movement. For example, in addition to information processing terminals and portable music players that are always in network communication, portable game machines that are capable of network communication, devices that are equipped with GPS and can wirelessly output current position coordinates in real time, such as cameras and watches Good.

  The monitoring device 20 identifies each mobile unit 10 in the local area L based on the individual identification information included in the mobile unit information, and the mobile unit 10 based on the temporal change in the position information of the information communication terminal 11. The moving direction and moving speed are calculated. The monitoring device 20 extracts the moving body 10 whose relative distance is approaching from the calculated moving direction and moving speed of each moving body 10. The monitoring device 20 approaches each information communication terminal 11 of the moving body 10 approaching each other in the direction in which the other-side moving body 10 approaches in the traveling direction thereof, until it encounters the other-side moving body 10. The approach information including at least the predicted time and the type of the counterpart mobile body 10 as the counterpart mobile body information is notified.

  When the information communication terminal 11 receives the approach information, the information communication terminal 11 outputs the other party mobile body information by an informing means such as an external speaker or a display device provided in the information communication terminal 11. When the information communication terminal 11 is a navigation device or a mobile phone, the other party mobile body information is displayed on the display unit with symbols such as characters and a map, and an attention is given by voice announcement. Further, when the information communication terminal 11 is a mobile phone, the information communication terminal 11 may be notified with vibration by a vibration function. At this time, the announcement including the approaching direction, the estimated time to encounter, and the type of the moving body 10 on the other side is easy to understand without looking at the display unit.

  An example of voice announcement as partner-side mobile body information output from the information communication terminal 11 by receiving the approach information will be given below. For example, in Fig. 1, from the navigation device equipped with the vehicle 10A, "Please be careful. An automobile (vehicle 10D) approaches the intersection 20m ahead from the left. And when it catches up with the bicycle (10B) ahead. , The oncoming vehicle (vehicle 10C) will come. " Further, in FIG. 1, a voice announcement such as “Please be careful. The car (vehicle 10A) catches up from behind after 10 seconds” is output from the mobile phone equipped with the person who drives the bicycle 10B. Further, in FIG. 1, the navigation device equipped with the vehicle 10 </ b> C announces “Please be careful. There is a possibility that the car (vehicle 10 </ b> A) coming from the front after 10 seconds may pass the bicycle (10 </ b> B)”. May be output. In FIG. 1, from the navigation device equipped with the vehicle 10D that makes a left turn, “Please be careful. A pedestrian (10E) crosses the pedestrian crossing that has made a left turn. The voice announcement saying “I will pass.” Is output and the mobile phone equipped with the pedestrian 10E trying to cross the pedestrian crossing “Please be careful. When crossing the pedestrian crossing, the car (vehicle 10D) "I'll come."

  The monitoring device 20 requests each information communication terminal 11 to input to the information communication terminal 11 as response information that the access information has been confirmed. The response information can be input by one of the operation buttons provided in the information communication terminal 11 or a button displayed on a display screen having a built-in touch panel. At this time, when there are a plurality of mobile bodies 10 on the other side that approach, the monitoring device 20 requests input of response information for all of them.

  When the moving body 10 is a vehicle and is equipped with a braking device, an accelerator pedal position sensor (APS), a handle angle sensor, etc. with which the information communication terminal 11 is linked via an ECU or the like, the opening degree of the APS is reduced. In addition to the operation or the operation of operating the braking device, the response information may be input by an operation of turning the handle to avoid contact or collision.

  When the monitoring device 20 acquires response information from each information communication terminal 11, the monitoring device 20 reports this response information to the information communication terminal 11 of the approaching mobile body 10. When response information is not input even if a certain period of time has passed since the approach information was notified, or when response information is not input from at least one information communication terminal 11, the monitoring device 20 Warning information is output to the information communication terminal 11 of the mobile body 10.

  For example, in FIG. 1, the targets of the approach information for which response information should be input for the vehicle 10A are the vehicle 10D, the bicycle 10B, and the vehicle 10C. The target of the approach information for which response information should be input for the bicycle 10B is the vehicle 10A. The approach information to which response information should be input for the vehicle 10C is the vehicle 10A and the bicycle 10B. The approach information to which response information should be input for the vehicle 10D is the pedestrian 10E and the vehicle 10A.

  However, at this time, when the approach information is not notified, such as the bicycle 10B and the vehicle 10D, the bicycle 10B and the pedestrian 10E, the vehicle 10C and the vehicle 10D, or the vehicle 10C and the pedestrian 10E, the response information is also not obtained. . Therefore, even if the vehicle 10A does not input only the response information for the vehicle 10D, if the bicycle 10B inputs the response information for the vehicle 10A and the vehicle 10C inputs the response information for the bicycle 10B and the vehicle 10A, the monitoring is performed. The device 20 does not output warning information to the vehicle 10A, the bicycle 10B, and the vehicle 10C. However, since the vehicle 10A does not input response information for the vehicle 10D, the monitoring device 20 outputs warning information to the vehicle 10A and the vehicle 10D. Further, when the information communication terminal 11 that outputs the warning information is a mobile phone, the vibration function may be used for notification with vibration.

  The same warning information may be output to the information communication terminals 11 of all the mobile bodies 10, or the warning information for the mobile bodies 10 in which the response information is input to the information communication terminals 11 and the response information to the information communication terminals 11. You may change the content with the warning information with respect to the mobile body 10 which is not input. The information communication terminal 11 that has received the warning information displays a symbol such as a character or a map on the display unit, and notifies a warning by a voice announcement. An example of a voice announcement when warning information is received is given below.

  For example, in the case of the vehicle 10A and the vehicle 10D in FIG. 1, “the car (vehicle 10A) passing through the road ahead of the pedestrian crossing recognizes you with respect to the vehicle 10D that is the moving body 10 that has input the response information. A voice announcement saying “No.” is output, and the vehicle 10A, which is the moving body 10 that does not input response information, is warned. Check the car (vehicle 10D) coming from the left at the intersection ahead. . "Is output.

  Furthermore, when at least one of the moving bodies 10 that are close to each other is a vehicle that includes an electronically controllable braking device linked to the information communication terminal 11 and no response information is input from each of the information communication terminals 11, the monitoring device 20 Not only outputs warning information to the information communication terminal 11 of each moving body 10, but also operates a braking device of the vehicle to decelerate the vehicle. When the moving bodies 10 approach each other, they may be completely stopped. You may decelerate by fuel cut etc. besides operating a braking device. Until the warning information is cleared, the vehicle is restricted from accelerating.

  For example, in the situation of FIG. 1, the vehicle 10A includes a braking device linked to the information communication terminal 11, the vehicle 10C does not include such a braking device, and the bicycle 10B does not input response information for the vehicle 10A. In this case, warning information is output to each of the vehicle 10A, the bicycle 10B, and the vehicle 10C, and the vehicle 10A is further decelerated by the braking device. That is, the vehicle 10A is suppressed from overtaking the bicycle 10B until it passes the vehicle 10C that is an oncoming vehicle. Further, the vehicle 10C includes a braking device linked to the information communication terminal 11, and the vehicle 10A does not include such a braking device, and any of the vehicle 10A, the bicycle 10B, and the vehicle 10C inputs response information. Otherwise, if there is a sufficient distance that does not pass the vehicle 10C before the vehicle 10A passes the bicycle 10B, the monitoring device 20 operates the braking device of the vehicle 10C to decelerate the vehicle 10C.

  In addition, when the mobile bodies 10 that are close to each other are vehicles having electronically controllable braking devices linked to the information communication terminal 11 and no response information is input from each of the information communication terminals 11, the monitoring device 20 Outputs warning information to each information communication terminal 11 and operates a braking device of a vehicle having a low traffic priority in the local area L among the approaching vehicles to decelerate the vehicle.

  For example, in the situation of FIG. 1, both the vehicle 10A and the vehicle 10C have a braking device linked to the information communication terminal 11, and any of the vehicle 10A, the bicycle 10B, and the vehicle 10C does not input response information. In this case, the braking device of the vehicle 10A to be the moving body 10 having a low traffic priority in this situation is operated. The vehicle 10A is restricted from passing the bicycle 10B until it passes the vehicle 10C.

  Further, in the situation shown in FIG. 1, when both the vehicle 10A and the vehicle 10D include a braking device linked to the information communication terminal 11, the monitoring device 20 sets the braking device for the vehicle 10D to be the moving body 10 having a low traffic priority. The vehicle 10A is passed first by decelerating by operating or stopping before the intersection K1.

  When the vehicle 10D is an emergency vehicle or the like and the traffic priority is high regardless of the width of the road or the like, the braking device of the vehicle 10A is operated and the vehicle 10D is passed first. Further, when the vehicle 10D is an emergency vehicle, the range of the moving body 10 to which the approach information is notified is expanded. In the case of the situation in FIG. 1, vehicles 10A and 10C, bicycles 10B and 10P, and pedestrians 10E, 10F, 10G, and 10M are included as moving bodies 10 that are notified of approach information. In this case, in the approach information and warning information, the vehicle 10D is an emergency vehicle, and the navigation device that is the information communication terminal 11 of the vehicles 10A and 10C and the mobile phone that is the information communication terminal 11 of the person who drives the bicycles 10B and 10P. The data is output to the mobile phone that is the information communication terminal 11 of the pedestrians 10M, 10E, 10F, and 10G that may cross the road that can be the course of the vehicle 10D.

  An example of an audio announcement that is output when each information communication terminal 11 receives approach information and warning information related to an emergency vehicle (vehicle 10D) started from the monitoring device 20 is given below. For example, in the situation of FIG. 1, the emergency vehicle (vehicle 10D) enters from the left at the intersection (K1) ahead of the vehicle 10A and the bicycle 10B. Reduce the speed and stop at the shoulder. The voice announcement is output. Similarly, a voice announcement “An emergency vehicle (vehicle 10D) enters the intersection (K1) ahead from the right. Reduce the speed and stop at the shoulder” is output to the vehicle 10C. In addition, a voice announcement such as “Emergency vehicle passes. Please be careful” is output to pedestrians 10M, 10E, 10F, and 10G. After a certain period of time has elapsed, if deceleration and braking operations are not confirmed by operating the APS or the brake pedal in the vehicles 10A and 10C, the monitoring device 20 further activates and stops the braking devices of the vehicles 10A and 10C.

  The object of the moving body 10 approaching each other is not limited to the case of including a vehicle. For example, in the situation of FIG. 1, a bicycle 10B and a pedestrian 10E, a pedestrian 10G and a runner (pedestrian 10H), and the like correspond thereto. An example of a voice announcement output from a mobile phone serving as the information communication terminal 11 by receiving the approach information is given below. For example, a voice announcement “Please be careful. A bicycle (10B) is coming from the left front” is output to the pedestrian 10E who is about to cross the pedestrian crossing. A voice announcement “Please be careful. A pedestrian (10E) crosses the pedestrian crossing to the left of the intersection (K1)” is output to the bicycle 10B. In addition, a voice announcement “A person jogging (runner (pedestrian 10H)) will come out from the rear left alley (R3)” will be output to the pedestrian 10G, and the runner (pedestrian 10H) will be output. "Please note. There is a pedestrian (10G) on the left after leaving the alley (R3)."

  At least one of the moving bodies 10 approaching each other is a pedestrian, and the rest is a vehicle equipped with an electronically controllable braking device and a horn linked to the information communication terminal 11, and the response information is received from the information communication terminal equipped by the pedestrian. Is not input, the monitoring device 20 sounds a horn and outputs warning information to each information communication terminal 11. When the vehicle is approaching too much, the speed of the vehicle is reduced by the braking device.

  In the situation of FIG. 1, the relationship between the pedestrian 10E and the vehicle 10D corresponds to the relationship between the pedestrian and the vehicle including the horn. In addition, when the bicycles 10B and 10P are pedestrians, the vehicles 10A and 10C correspond to vehicles equipped with a horn. Under these circumstances, when the vehicles 10A, 10C, and 10D are accompanied by deceleration, stop, or avoidance operation when inputting response information, and the relative distance is maintained at a certain distance or more, the monitoring device 20 warns. When outputting information, it is not necessary to decelerate the speed of the vehicles 10A, 10C, and 10D.

  Further, the traffic monitoring system 1 includes a camera 21 that captures images in the local area L, an image analysis device 22 connected to the camera 21, and an alarm device 23 connected to the monitoring device 20. The image analysis device 22 extracts a moving body (pedestrian 10N) that is not equipped with the information communication terminal 11 based on the video acquired by the camera 21, and sets position information and type of the moving body (pedestrian 10N). . The position information is calculated from the position of the building or the like taken with the moving body. In order to easily calculate the position information, a reference mark may be placed in advance in the shooting range of the camera 21.

  The alarm device 23 is installed at a main position in the local area L. In the situation of FIG. 1, the alarm 23 is installed at the corner on the left-hand side from the road R1 with poor visibility, or at the corners on both sides of the entrance / exit of the alley R3. The alarm device 23 is used in combination with a flash lamp or the like, in addition to notifying the direction in which the approaching moving body is present by sound. By using a flash lamp, it is easy to detect visually from a distance, and does not cause noise at night.

  By providing these, the traffic monitoring system 1 provides access information to each mobile body even if the mobile bodies 10 that are close to each other include at least one mobile body that is not equipped with the information communication terminal 11. Response information can be acquired. For example, in the situation of FIG. 1, when the pedestrian 10N turns right at the intersection K1, if the moving body 10 is approaching so as to approach the intersection K1, the moving body (pedestrian 10N) without the information communication terminal 11 As approaching information, an alarm is output by sound or light from the alarm device 23 installed at the corner facing the intersection K1. When the image analysis device 22 confirms that the pedestrian 10N is approaching the intersection K1 while looking at the alarm device 23 based on the video imaged by the camera 21, the mobile object that does not have the information communication terminal 11 (walking) The monitoring device 20 treats this operation of the person 10N) equivalent to the response information being input. Therefore, by notifying the information communication terminal 11 of the moving body 10 approaching the pedestrian 10N of the response information obtained based on the movement of the pedestrian 10N, it can be understood that the response information is input to each other. it can.

  When response information is not input from the information communication terminal 11 of the mobile body 10, that is, a certain time has elapsed since the mobile body 10 approaching the pedestrian 10N receives the approach information at the information communication terminal 11. However, if no response information is input, the alarm device 23 is in a direction in which a mobile body (pedestrian 10N) not equipped with the information communication terminal 11 approaches the mobile body 10 equipped with the information communication terminal 11. Causes an alarm to be output. By outputting this warning, it can be seen that the pedestrian 10N, which is a mobile body that is not equipped with the information communication terminal 11, does not input response information from the counterpart mobile body. In the case of outputting a warning, it is easy for the pedestrian 10N to understand if a warning, a light emission pattern, or a light emission color different from the case where the alarm 23 is operated based on the approach information.

  Next, the control of the monitoring device 20 that determines whether or not each moving body 10 is approaching each other in the various situations described above and outputs the approach information and the warning information will be described with reference to FIG. The monitoring device 20 acquires the moving body information in the local area L that has jurisdiction (S1). One antenna for acquiring the mobile object information may be provided in the center so as to cover the entire local area L, or in order to accurately capture the position of the mobile object 10 in addition to the mobile object information. At least three of them may be dispersed.

  When the monitoring device 20 acquires the moving body information (S1), the monitoring device 20 determines whether the moving body is in the local area based on the individual identification information and position information included therein (S2). If it is determined that the position information is not the local area L, it is determined whether it is outside the local area L (S3), and if it is outside, the acquired mobile body information is deleted (S4) and the process returns to the start. When it is determined that the position information is not outside the local area L, the mobile body information of the same mobile body is acquired again based on the identification information.

  When the position information is in the local area L, the mobile body 10 that outputs this mobile body information is recognized as a mobile body that has entered the local area L (S5), and the moving direction and moving speed are determined based on the change over time. Calculate (S6). Note that the moving direction and moving speed of the moving body 10 may be calculated by the information communication terminal 11 and may be included in the moving body information and output.

  Further, based on the type of the mobile body included in the mobile body information, it is determined whether the information communication terminal 11 equipped on the mobile body 10 is a navigation device (S7). When the information communication terminal 11 is a navigation device, the identification number of the navigation device in the local area L is assigned (S8), and the mobile body 10 is registered as “vehicle (automobile, motorcycle, etc.)” (S9). In addition, as information on the type of moving body included in the moving body information output from the navigation device, whether it is an automobile, a motorcycle, or a large vehicle such as a truck is set in advance. The identification number of the navigation device may be further subdivided.

  If it is determined that the information communication terminal 11 is not a navigation device, an identification number of a mobile phone or the like in the local area L is given as the information communication terminal 11 installed in the mobile body 10 is a mobile phone or the like ( S10). Here, in order to exclude the mobile body information output from the mobile phone carried by the person on the vehicle, the monitoring device 20 is configured such that the mobile body to which the identification number such as a mobile phone is assigned is the navigation device. It is determined whether or not the same position as that of the moving body 10 to which the identification number is assigned is moving at the same speed (S11). The identification numbers of the moving bodies moving at the same speed at the same position are integrated into the identification numbers of the navigation device (S12), and the identification numbers of the integrated moving bodies are deleted (S13). In addition, until a moving body registered as a vehicle leaves the local area L or stops in the local area L for a predetermined time or longer, the moving body in which these identification numbers are erased enters the local area L. In order to avoid re-recognition as a mobile object, the identification information included in the mobile object information output from the information communication terminal 11 of the mobile object to which the deleted identification number has been assigned is stored and read based on this. The mobile object information is selected and the information once deleted in S13 is excluded.

  The identification numbers of mobile bodies that are not moving at the same speed as the identification numbers of the navigation device are recognized as independent mobile bodies. At this time, registration is made in “pedestrian”, “bicycle”, “motorcycle”, and “automobile” based on the moving speed calculated for each identification number (S14). At this time, if multiple identification numbers are moving at the same speed at the same position, one person moves on a vehicle (such as an automobile) that has multiple mobile phones or is not equipped with a navigation device. It is assumed that In such a case, the identification number is deleted while leaving one of the plurality, for example, the one having the smallest identification number.

  When each moving body 10 is registered based on the acquired moving body information, a group of moving bodies 10 that are close in relative distance is extracted from all the registered moving bodies 10 (S15). It is determined whether there is a possibility of a collision in the local area L based on the vector based on the moving speed and moving direction of each moving body 10 in the group and the map information of the local area L (S16). When the vectors do not cross like a vehicle traveling in the oncoming lane, when the roads are intersecting in the vector but are gently curved in the map information, or when pedestrians walking on the same sidewalk, When it is determined that there is no possibility of a collision, the group is released from the monitoring target.

  If it is determined that there is a possibility of collision between the mobile bodies 10 in the group, the approach information is output to the information communication terminal 11 of each mobile body 10 in the group and response information is requested (S17). When response information is input to the information communication terminal 11, it is notified that the response information has been input to the counterpart mobile body 10, that is, that the information has been mutually recognized. Confirm whether response information has been obtained from the information communication terminals 11 of all the mobile units 10 in the group before the fixed time has passed (S18), and if all the response information has been obtained, continue to call attention by approach information (S19).

  When all the response information is not obtained when a certain time has passed, that is, when no response information is obtained, it means that the mobile bodies 10 in the collision course cannot recognize each other. Therefore, in that case, warning information is output to each information communication terminal 11 (S20). The details of approach information and warning information are as described above. Further, when the vehicle is equipped with a braking device or the like linked to the information communication terminal 11, immediately after outputting the warning information, the vehicle braking device or the like is operated (S21) and decelerated. In this group, it is confirmed whether there is a possibility of a new collision (S16). If a possible collision has occurred, the steps from S17 to S21 are repeated, and if the possibility of collision is lost, the mobile body information in the local area L is newly acquired (S1). If there is no new moving body information, a group that has already been approached by moving bodies already assigned identification numbers is extracted (S15).

  The first embodiment has been described with the traffic monitoring system 1 installed for the intersection K1, roads R1 and R2 where no sidewalk is provided, road R1 and alley R3 with poor visibility. The traffic monitoring system 1 is not only permanently installed in such a local area L, but also temporarily in sections that are different from normal road conditions, such as sections that can be queued by events, school zones, construction sections, etc. The monitoring device 20 may be installed and the local area L may be set. At this time, since the camera 21 and the image analysis device 22 are also used in combination, accurate access information can be obtained, so it is easy to ensure safety.

  A traffic monitoring system 1 according to a second embodiment of the present invention will be described with reference to FIG. FIG. 3 schematically shows an area where two traffic monitoring systems 1 are adjacent. Since each traffic monitoring system 1 has the same function as the traffic monitoring system 1 in the first embodiment, the first embodiment is referred to for details thereof. When one traffic monitoring system 1 is mainly viewed, the monitoring device 20 of the other adjacent traffic monitoring system 1 corresponds to the adjacent monitoring device. The local area L managed by the monitoring device 20 of each traffic monitoring system 1 has an overlapping boundary zone Lz.

  In the traffic monitoring system 1 of the second embodiment, the monitoring device 20 is linked to the monitoring device 20 of the adjacent traffic monitoring system 1 as shown in FIG. Communication between the two monitoring devices 20 may be directly connected as shown in FIG. 3, may be connected via a network, or may be communicated wirelessly. A plurality of monitoring devices 20 may be integrated and managed by the area management device.

  The monitoring device 20 calculates the moving speed and moving direction based on the moving body information of the boundary moving body 10Z located in the boundary zone Lz. As a result, when the boundary moving body 10Z does not approach any of the other moving bodies 10 in the local area L that has jurisdiction, the monitoring apparatus 20 uses the moving body information of the boundary moving body 10Z as a neighboring monitoring apparatus 20. Transfer to

  As described above, when a plurality of traffic monitoring systems 1 are adjacent to each other, the monitoring device 20 of each traffic monitoring system 1 is linked to smoothly access information related to a moving body that straddles two adjacent local areas. Can be processed. Further, the approach information left from both traffic monitoring systems 1 does not become complicated for the boundary moving body 10Z located in the boundary zone Lz of the local area L. It should be noted that the size of the local area L of the adjacent traffic monitoring system 1 is such that a plurality of moving objects are not simultaneously located in the boundary zone Lz, and roads and intersections with poor visibility are not present in the boundary zone Lz. Are set respectively.

  In any of the traffic monitoring systems 1 in the first and second embodiments, in order to manage a vehicle parked on the road, the monitoring device 20 is an information communication terminal at a point where the moving body 10 that is a vehicle stops. When the mobile body information is not output from 11, the mobile body 10 is in its position, and the approach information is notified to the information communication terminal 11 of another mobile body 10 approaching the mobile body 10. By doing so, even if a vehicle is parked immediately after turning an intersection with poor visibility, these can be reliably notified to the moving body 10 traveling on a road such as a vehicle, a bicycle, or a motorcycle.

  Furthermore, in the traffic monitoring system 1 according to the first and second embodiments, an unexpected situation occurs such as a vehicle traveling ahead suddenly stops, or a pedestrian or bicycle jumps out on the road, and this is used as approach information. When sufficient time for notifying and acquiring response information cannot be secured, the traffic monitoring system 1 notifies the warning information by the monitoring device 20. At this time, if the vehicle has a braking device with which the information communication terminal 11 is linked, the braking device is operated together with the warning information.

  In addition, when the stopped vehicle starts, since approach information is previously alert | reported with respect to the information communication terminal 11 of the stopped vehicle, it can prevent that it becomes an unexpected situation. When a braking device is linked to the information communication terminal 11, the braking device may be operated so as not to start until the approach information for the stopped vehicle is resolved.

  The traffic monitoring system 1 is not limited to those described above, such as vehicle-to-vehicle, vehicle-to-pedestrian, pedestrian-to-bicycle, and vehicle-to-bicycle. As long as it enters the local area L while transmitting moving body information including at least position coordinates, the traffic monitoring system 1 can notify the pedestrian or vehicle equipped with the information communication terminal 11 of this. it can. For example, if a GPS transmitter that outputs position coordinates is provided on the collar of a pet such as a dog or cat, the traffic monitoring system 1 can protect the pet when the pet jumps out on the road.
